It really isn't if you compare it to our world, from the survey I found with a quick Google search Spain was the highest with only 3,4% in 2021. But I agree with you in such a short time the acceptance in strict and traditional countries won't change fast.Only 2% gay marriage? Sounds a little low, oh well give them more time than 4 years I guess
It is a hypothetical scenario for the sake of the storyI'm a little lost, the TV says gay marriage has been legal in Japan for 4 years, but gay marriage isn't generally legal in Japan? The closest would be the 2021 court decision saying that the current ban isn't constitutional which didn't actually legalize gay marriage and isn't universal across Japan, so is this manga set in an alternate timeline or the future?
